M/S Finlandia is a cruiseferry built in 2001 and owned by Eckerö Line. The ship operates the route between Tallinn and Helsinki. M/S Finlandia has a length of 175 meters and carries 2080 passengers and 610 cars. The ship has a max. speed of 27 knots. 

Our solution for M/S Finlandia includes optimization and automatization of HVAC, pump control, and engine room ventilation. In addition, a new, user-friendly control system with focus on comfort and energy saving was installed. All work performed during regular operations and no need to disrupt or dry dock the vessel.

CONTROL SYSTEM
A new control system for HVAC, pre-and re-heat heating, pumps, and chillers were installed. The control system from Kongsberg was reprogrammed for more economical use of the Engine Room Ventilation with VFDs. The system is adjusted specifically for M/S Finlandia and targets power consumption, comfort, and usability.

HVAC
For the HVAC unit an installation of VFDs was made for cabin-, public-, and service units each with their own individual regulation by, temperature, Co2 or/and Humidity. Recirculation dampers and VVX were included in the steering to achieve the most economical drift meanwhile increasing comfort. Drives for electrical motors and 20 new VDS for VVX were installed. The airflow of the two-channel system consisting of exhaust- and supply air was balanced. All of this is monitored by an automatic steering system with a focus on comfort and energy efficiency.

ENGINE ROOM VENTILATION
24 drives were installed for machinery spaces. Installation of temperature-, pressure- and differential pressure sensors. The new VFD:s are integrated into the control system from Kongsberg which is reprogrammed to regulate temperature and differential pressure in order to always keep the lowest energy consumption while keeping the climate in the engine room areas within required values. 

PUMPS
VFD’s were installed for Re-Heat, Pre-Heat, SW, LO, and AC SW. Temperature-, pressure-, and differential pressure control. Pumps are integrated into Kongsberg and the function reprogrammed. 

HEAT RECOVERY
The original heat recovery system from ME Cooling water was rebuilt and expanded to include heating potable water and pre-Heating. The system was integrated into the existing control system. 

The calculated pay-off time for the whole project is XX years.
